Kettra turns every habit into a chain. Each day you tick off is one link. The chain grows for as long as you keep going, and that is the thing you will not want to break. TICK IT OFF WITHOUT OPENING THE APP • The home screen widget shows your chains and takes the tap right there • Lock screen widgets, for the glance in between • A second widget shows how much you kept over weeks or months • Straight from the notification • With Siri: "Tick off a habit in Kettra" • And of course with one tap in the app YOUR RHYTHM • Daily, on fixed weekdays, or a few times a week • Several times a day, with a count instead of a tick • Pause for a holiday or an illness: paused days do not break the chain NOTHING IS SET IN STONE • Fill in or take back a past day with a long press • Add a note to a day when the chain had a reason • Rename, reorder, delete, whenever you like WHAT YOU SEE • The week as a grid of chains, every habit in its own colour • Current chain, longest chain, and the total • Milestones from 2 days to 365, with the next one always in view REMINDERS THAT FOLLOW YOU • Fixed times, set per habit • Optionally, the reminder moves to the time you actually tick the habit off • "Chain at risk": one message, on the day there is genuinely something to lose YOUR DATA STAYS YOURS No account, no server, no sync, no ads, no trackers. Everything lives on your device. You can export all of it as a CSV file at any time, and if you delete the app the entries go with it. LIGHT OR DARK Kettra follows your phone, or you set it yourself.
